Ah I see what you mean.
Yes my original problem is related to what you suggested. My idea was to have a subscriber-publisher type system where components can easily send data to each other in a decoupled way. Delegates was just one of the ways I imagined might working.
I know that at a certain point you have specify things but I wanted to come up with a solution where the hard coding is minimized and works well with blueprints. So at the end I’d have a system where components can easily communicate with each other and you can modify/extend effortlessly.
I have read through the readme it seems like an interesting solution I might check it out in practice.
